Research on dry structure floor radiant heating system

摘要

The research provided a new dry structure low- temperature hot water floor radiant heating system,which was to put heat pipes in enclosed space. It discussed heat transfer mechanism of this paving type and calculated the changes of some factors having impacts on thermal characteristics and indoor thermal environment.The factors included material and thickness of the floor structure, pipe diameter, pipe distance and distribution,supply water condition and outdoor temperature. All of these were validated by experiments. It could be concluded that it was feasible to use poor thermal resource in Beijing and the other similar areas, which was the same as the filling floor heating.
